SPRING BED AND SEAT BOTTOM.

SPECIFICATION forming part of Letters Patent No. 639,222, dated December 19, 1899. Application filed January 16, 1899. $erial 110.702.3423. (N model.)

, of the United States, residing at Kenosha, in

the county of Kenosha and State of WVisconsin, have invented certain new and useful Improvements in Spring Bed and Seat Bottoms, (Case A;) and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

For convenience in making cross-reference this application is designated Case A, and four other applications for Letters Patent for bed-bottoms executed by me of even date herewith, are designated, respectively, Case B, Case C, Case D, and Case E.

This invention relates particularly to spring bed-bottoms formed of vertical spiral springs united horizontally by tie-rods.

The improvement involves the use of a new form of tie-rod which permits the use of the simplest form of vertical spiral springs and which allows the ready assembling of the parts of the bed-bottom to constitute the finished structure. There is economy in the ready assembling of these parts and there is also economy in the use of a simple form of the spiral spring.

My improvement results in a structure which has a high degree of strength, a distribution of strain applied at any particular point, and an even surface.

In the accompanying drawings, Figure 1 is a plan of a portion of a bed-bottom embodying myimprovement. Fig. 2 is a similar view embodying a modification of the tie-rods and assemblage of the parts of the bed-bottom. Figs. 3, 4, 5, 6, 7, 8, and 9 illustrate other modifications. V

Inasmuch as the general construction of bed-bottoms of this class is well known I deem it sufficient to illustrate only portions of bedbottoms showing the application of my improvement.

Referring first to Fig. 1, A is a rectangular frame forming the margins of the bed-bottom. "This frame may be of wood or metal; but it is preferably made of metal rods or bars somewhat heavier than the metal of the springs and tie-rods. B B are the springs. These are arranged in rows parallel to the sides of the frame A and are in vertical position and of spiral form, the upper end of each being formed into acomplete ring B by knotting or in any suitable manner. The spring may be cylindric in outline or it may be conical or double conical. As already stated, it is the object of the invention to embody the well-known forms of vertical bed-sprin gs into a bed-bottom of superior quality and the parts of which may be readily made and readily assembled.

versely'across the bed-bottom and having its ends suitably attached to the frame A'and engaging two rows of springs B.

In Fig. 1 the tie-rods are shown extending above or over the rings B of the springs of one transverse row and provided with V- shaped folds or loops C, extending through the ring of that spring and through the ring of the adjacent spring of the next transverse row, the loop being bent vertical, so as to extend through the last-mentioned ring out of the plane of the latter. The transverse rows of springs B adjoining the frame A are united to said frame by one of said tie-rods, the loops C extending partially around the said frame. Another set of tie-rods D D, which for convenience I will term key-rods,

are arranged at right angles to the tie-rods C.

These are straight and extend centrally over the longitudinal rows of springs B and beneath the vertical part C of each loop C in the row of springs traversed by said key-rod. The ends of the key-rod D may be suitably secured to the frame A, preferably in engagement with a loop C, engaging the frame at that point, the rod reaching through the loop. It will 110W be seen that the bed-bottom illustrated by said Fig. 1 consists of only four kinds of partsnamely, the frame A, springs B, tie-rods C, bearing the loops, and the straight key-rods D-and it will now be nnderstood that the assembling of these parts to form the complete bed-bottom is a simple process involving only the use of the hands and a simple bending-tool for securing the ends of the tie-rods and key-rods. The frame may C is a tie-rod extending transbe first put into position and the springs then placed in rows within the frame. The tie-rods B are then put into position with reference to the springs and the frame and the ends of said tie-rods bent around the frame or secured in any other suitable manner. The key-rods I.) are then successively put into position by passing them over the springs transversely to the tie-rods O and beneath the loops of the latter, the ends of said key-rods D being secured, as by bending around the frame or otherwise. This results in a very positive interconnection of the springs and the forming of such a surface as will not yield unduly at any one point, pressure at any point involving the depression of a considerable area of the bed-bottom surface. The fact is also to be noted that the key-rods D, extending midway over the rings B, prevent the central portion of the spring from pushing upward through the ring B, as is sometimes the case when the upper portion of the springis left unprotected. The key-rods D may have upward bends d where they cross the rings B, as shown in Fig. 5, whereby recesses are formed to receive said rings.

The form of bed-bottom shown in Fig. 2 differs only from the form shown in Fig. 1 in that the tie-rods E, corresponding to the tie-rods C of Fig. 1, pass beneath the rings F of the springs F, the springs F and the rings F corresponding to the springs B and rings B, respectively, of Fig. 1, while the loops E pass over instead of under the rings of the springs under which said tie-rods pass, and the marginal tie-rod E has its loops E extending over instead of under the frame G, and they are bent nearly once around the frame, so as to again rise sufficiently to receive the key-rods H H.

The modification shown in Fig. 3 differs only from the form shown in Fig. 1 in that the loop C, after passing beneath the springring upon which its tie-rod rests, passes over the ring of the adjacent spring, and its vertical part extends downward through the latter ring, and the key-rod D, after extending over the first ring, extends beneath the second.

In Fig. 4 the frame A is omitted. The ends of the tie-rods C are wound around the springrings or otherwise secured, and the loops C of the outer tie -rod are bent around the spring-rings. On the two upper spring-rings at the left the tie-rod passes over the springring and the loops pass downward through and then upward over the ring. On the spring at the left the loop comes first upward through the ring and then downward around it. The ends of the key-rods engage both the loop and the ring in the same manner that they engage the loop and frame in Figs. 1 and 2. y

In Figs. 1, 2, 3, and at the loops are integral with the tie-rods. In Figs. 6, 7, 8, and 9 the loops are in position and engagement, as in Figs. 1, 3, and 4, but they are not integral ssaaaa with the tie-rods. They are separate pieces suitably attached to the tie-rods and extending laterally to engage the two rows of springs, substantially as shown in Figs. 1, 3, and 4.

Figs. 6 and 7 illustrate the same construction, the former being a plan and the latter a vertical section. I is a spring, and I is its ring. J is a transverse tie-rod extending over said ring, but having suitably-spaced upward bends J, which allow the main portion of the tie-rod to rest below the level of the ring I. J is a loop formed at its outer end like the loop shown in Figs. 1, 3, and 4, while its inner ends extend beneath the ring I, over the tie-rod J, and around the latter. The keyrod K passes over the ring I and beneath the tie-rod J at the middle upward bend J and beneath the loop J In the form shown in Figs. 8 and 9 the construction is like that shown in Figs. 6 and 7, excepting that the inner ends of the loop pass a second time beneath the ring of the spring and then around the tie-rods at the upward bends of the latter. In said Figs. 8 and 9 L is the ring of the spring. L is the transverse tie-rod, having the three upward bends L corresponding to the upward bends J of Figs.

6 and 7. L is the loop, and M is the key-rod.

It will be seen on making a comparison of these several figures that there is in each variation of form a tie-rod having lateral loops extending through two spring rings and around key-rods.

In all the forms the loop passes or enters the plane of the spring-ring only far enough to let the key-rod pass under strain.

It will be understood that my invention may be applied to spring-seats, and that the foregoing description is applicable to springseats as well as to spring bed-bottoms.

The construction illustrated by Fig. 2 is made the subject-matter of the application designated as Case B, to which reference has been made. The forms illustrated by Figs. 6, 7, 8, and 9 are made the subject-matter of the application designated as Case C, and the form illustrated by Figs. 8 and 9 is made the subject-matter of the application designated as Case D. The form illustrated by Fig. 4, the same being a structure not having the marginal frame, is made the subject-matter of the application designated as Case E.
